Application filediehruary 10, 1928. Serial No 253,491.

This invention relates to'a guard or guide especially designed for useinconnection with electric lamp sockets of the pull chain type, the 7primary object of the invention being to provide meansfor guarding thechain against cont-act with-the shade holder mounted on the lamp socket,or other portions of the socket, to prevent the free operation of thepull chain.

Another important object of the invention is to provide a device of thischaracter which may be readily and easily positioned, the device beingsupplied with a clamping member to clamp the chain guard forming a partof the usual electric lamp socket, eliminating the necessity of usinsecuring screws or other complicated means for attaching the device.

lVith the foregoing and other objects in View, which will appear as thedescription proceeds, the invention resides in the com bination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention. 7

Referring to the drawing: 7

Figure 1 is an elevational view illustrat ing a lamp socket equippedwith a guard constructed in accordance with the inven tion.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a perspective view of the guard.

Referring to the drawing indetail, the reference character 5 designatesthe usual lamp socket which is supplied with a guard 6 guarding theopening through which the pull chain 7 operates.

The reference character 8 designates the usual shade supporting ringsupplied with openings 9 to ventilate the lamp.

The guard, forming the essence of the present invention is indicated bythe reference character 10 and includes a tubular body portion formed ofa length of sheet metal, the tubular body portion being split throughoutits length so that the pull chain with which the device is to be used,may be positioned within the body portion by forcing it through theslot, it being understood that the usual pull chain is supplied with aball at the free end thereof oi' a diameter that would not pass throughthe tubular body portion. Theupper edges of thesplit body portionarecurved as at 11, so that the chain when being positioned in the bodyportion, will be guided to'its' proper position by contact with thecurved edges.

Formed integral with the body portion is an extension 12 that is oiisetas at 13 so that when the device is positionedfthe opening of the bodyportion will lie in a'plane directly, below the chain guard 6,eliminating any possibility of the chain binding at the upper end of thebody portion where it passes into the body portion.

The extension 12 is formed with a slot 14 provided with a central curvedportion 15,

defining lateral gripping fingers to grip the guard 6 of the lamp-socketwith which the device is to be used. To position the device it is onlynecessary to force the extension over the guard 6, whereupon the fingersof the extension will be spread apart and will clamp the guard 6 to holdthe body portion 10 in position. 7

As shown by Figure 1' the body portion is extended through oneof theventilating openings of the shade support and the pull chain ispositioned therein with the result that the sections of which the "chainis formed will not catch on the edge of the opening through which itextends to prevent the pulling of the. chain to operate the switchcontrolled thereby.

I claim: 7

1. In combination with the pull chain and pull chain guard of a lampsocket, an elongated body portion, a clamping member at oneend of thebody portion and adapted to clamp around the pull chain guard toremovably connect the body portion to the lamp socket.

2. In combination with the pull chain and pull chain guard of a lampsocket, an extension chain guard including a tubular body portion a pairof spring fingers at one end of the body portion and said spring fingersadapted to clamp around the usual chain guard to removably secure theextension guard to the lamp socket. '2

3. In combination with the pull chain guard of a lamp socket, adepending extension guard embodying a split tubular member in which thechain of the socket is positioned, an extension at one end of thetubular member, and said extension adapted to be clamped to the pullchain guard of the lamp socket.

4. In combination with the pull chain guard of a lamp socket, and chainoperating therethrough, a removable extension guard including a splitbody portion the upper corners formed by the split in the body portionbeing cut away to guide the pull chain into the body portion and meansat the upper end of the body portion for clamping the body port-ion tothe pull chain guard.

5. In combination with the pull chain and uard of a lamp socket, anauxiliary guard 15 including a body portion through which the pull chainextends, and means for removably securing the auziiliar pull chain guardto the lamp socket.

6. In combination with the pull chain and pull chain guard of anelectric lamp socket, an extension guard including a body portion, anextension at the upper end of the body portion and olt'set with respectto the body portion, and means for removably eonmeeting the extension tothe pull chain guard.

In testimony that I claim the foregoing as my own I have hereto atlixedmy signature.
